After an Oklahoma inmate died during a botched execution, questions were raised surrounding the death penalty and its place in the penal system.

Here's a look at six past executions that went terribly wrong.

Aug, 10, 1982. Virginia. Frank J. Coppola. Electrocution.It took two 55-second jolts of electricity to kill Coppola. After the second jolt, Coppola's head and leg caught on fire.

March 13, 1985. Texas. Stephen Peter Morin. Lethal Injection.Because of Morin's history of drug abuse, it took 45 minutes of probing Morin's arms and legs to find a suitable vein.

October 16, 1985. Indiana. William E. Vandiver. Electrocution.The execution took 17 minutes and five jolts of electricity.

December 13, 1988. Texas. Raymond Landry. Lethal Injection.Shortly after the drugs were administered, the syringe came out of Landry's vein, spraying the deadly chemicals across the room.

July 14, 1989. Alabama. Horace Franklin Dunkins, Jr. Electrocution.After the first jolt failed to kill Dunkins, it was determined the cables had been connected improperly, making it impossible to dispense sufficient current to cause death.
